The universal basis of dick sizes with 6 inches being the median represented by a number 5 on the scale of 1 - 10, 10 being the biggest. The result is stated as a dicktric number. This also converts dick size from the metric system. Ex: median dicktric number of 5 would be 15.2 centimeters.

I thought I had a big penis but the after looking at the dicktric system, I realize that I am pretty undersized.

I used the dicktric system and found that my dick has a dicktric number of 6. Score.
